Error Code Err09 De-Longhi

Symptom / Description

Door lock mechanism failure

Root Cause

The oven's motorized door lock has failed to lock or unlock correctly, often an issue during or after a high-temperature cleaning (pyrolytic) cycle.

Repair Instructions

UNLOCKED

Allow the oven to cool completely. Try power cycling the appliance. If the door remains locked or the error persists, the door lock motor assembly likely needs to be inspected and replaced.
